There are two kind class types in sql query object model, one is raw parse tree node, the other is parsed node.&nbsp;</p>
<p class="Element10">
Raw parse tree node is created according to each rule in BNF file. All information during parsing phrase is collected into raw parse tree node.&nbsp;</p>
<p class="Element10">
&nbsp;</p>
<p class="Element10">
Some typical raw parse tree nodes are <a href="TLz_SelectStmt.html" target="topic">TLz_SelectStmt</a>,&nbsp;</p>
<p class="Element10">
<a href="TLz_InsertStmt.html" target="topic">TLz_InsertStmt</a>, <a href="TLz_DeleteStmt.html" target="topic">TLz_DeleteStmt</a>, <a href="TLz_UpdateStmt.html" target="topic">TLz_UpdateStmt</a>.&nbsp;</p>
<p class="Element10">
&nbsp;</p>
<p class="Element10">
Parsed node is manually created during the analyzing phase, and with more user friendly interface. but may lack of detail information in corresponding raw parse tree node.&nbsp;</p>
<p class="Element10">
&nbsp;</p>
<p class="Element10">
Some typical parsed nodes are <a href="TSelectSqlStatement.html" target="topic">TSelectSqlStatement</a>, <a href="TDeleteSqlStatement.html" target="topic">TDeleteSqlStatement</a>, <a href="TInsertSqlStatement.html" target="topic">TInsertSqlStatement</a>,<a href="TUpdateSqlStatement.html" target="topic">TUpdateSqlStatement</a>.&nbsp;</p>
<p class="Element10">
&nbsp;</p>
<p class="Element10">
Each parsed node has a corresponding raw parse tree node.&nbsp;</p>
<p class="Element10">
&nbsp;</p>
<p class="Element10">
You can always use RawNode property to find out the corresponding raw parse tree node if any.</p></div>
